The CAS-Poly U Joint Lab investigated topological phases of matter in strongly interacting systems. The study focused on the growth, engineering, and fabrication of devices using the Kagome lattice, known for hosting quantum states. The CAS team specialised in molecular beam epitaxy and scanning tunnelling microscopy, studied topological quantum phases in Kagome lattices. The lab was equipped with a scanning tunnelling microscopy system featuring a tunable vector magnetic field. This setup allowed the team to understand chiral or helical fermions in topological matter and interactions with symmetry-breaking orders by exploring quasi-particle interference and Landau quantisation behaviours.

The Poly U team focused on growing two-dimensional Kagome lattices and conducting low-temperature, high magnetic field transport measurements. They designed and fabricated Kagome magnets, characterising their properties, while the CAS team conducted STM studies and replicated the growth.
